Report #58562

[bug\_fix] npm ERR\! code ELIFECYCLE npm ERR\! errno 1 npm ERR\! [email protected] test: \`jest\` npm ERR\! Exit status 1

Scroll up in the terminal output or check the log file \(npm-debug.log or .npm/\_logs/\) to find the actual underlying error \(test failure, syntax error, missing file\) from the tool being run \(jest, webpack, tsc\). Fix that root cause. ELIFECYCLE itself only indicates the subprocess exited with non-zero status. Root cause: The script \(test, build, start\) invoked a command that failed, and npm is reporting the wrapper process exit code.

Journey Context:
You run \`npm test\` and immediately see red text 'npm ERR\! code ELIFECYCLE'. You panic thinking npm itself is broken. You see 'Exit status 1' but no clear stack trace. You scroll up and see a Jest test failure with a snapshot mismatch, or a TypeScript compilation error 'TS2345: Argument of type X is not assignable', or 'Module not found: Error: Can't resolve './missing' in webpack'. You realize ELIFECYCLE is just npm's way of saying 'the thing you ran crashed'. You fix the actual test, fix the TypeScript type, or add the missing import. When you run \`npm test\` again, it passes because the underlying tool no longer exits with code 1.

environment: Any Node.js/npm environment when running scripts \(npm run build, npm test, npm start\) where the underlying tool \(webpack, tsc, jest, eslint\) encounters an error. · tags: elifecycle exit-code npm-run-script debugging logs test-failure build-error · source: swarm · provenance: https://docs.npmjs.com/cli/v9/commands/npm-run-script and https://docs.npmjs.com/generating-and-checking-logs-of-npm-operations
